摘要： The invention generally relates to an improvement of conventional Hydraulically Power Assisted Steering system (HPAS-system) arranged to supply a steering assist force to the steering assembly of a vehicle as a response to a torque applied by a driver to the steering wheel. In such HPAS-systems a certain drivers torque always results in a certain assist force. The invention therefore discloses a valve that can be actuated to dynamically alter the steering assist force produced by the HPAS-system. This makes it possible to dynamically adjust the assist force so that an appropriate force may be delivered to fit the specific driving scenario.
摘要翻译：本发明一般涉及传统的液压动力辅助转向系统（HPAS系统）的改进，其被布置成作为对驾驶员施加到方向盘的扭矩的响应来向车辆的转向组件提供转向辅助力。在这种HPAS系统中，一定的驾驶员扭矩总是导致一定的辅助力。因此，本发明公开了一种可以被致动以动态地改变由HPAS系统产生的转向辅助力的阀。这使得可以动态地调节辅助力，使得可以输送适当的力以适应特定的驾驶场景。

摘要： Each cylinder of a hydrostatic hydraulic machine of the displacement type is preliminarily pressurized after the inlet port of the cylinder has been exposed to the low pressure side of the machine and before the inlet port of the cylinder is exposed to the high pressure side of the machine. The preliminary pressurization is effected by use of a separate pressure chamber containing a pressurized fluid that is rapidly discharged into the inlet port of each cylinder before the cylinder inlet port is exposed to the high pressure side of the machine. The separate pressure chamber is recharged from the high pressure side of the machine at a rate that is slower than the rate at which pressurized fluid is discharged from the chamber into the inlet port of a cylinder.

摘要： A method is provided for recuperating potential energy during a lowering operation of a load, wherein a hydraulic system is adapted to lift and lower the load. In the method, at least two energy recuperation modes are provided, one of the modes is selected in response to a current operating state, and the hydraulic system is controlled according to the selected mode.
